The sender domain has a DMARC Reject/Quarantine policy which disallows
sending mailing list messages using the original "From" header.
To mitigate this problem, the original message has been wrapped
automatically by the mailing list software.
Fixes: FS#2086
The logic for IS_TTY was broken, because it was testing stdin
instead of stdout.
MAKE_TERMOUT was introduced in GNU Make version 4.1 (05 Oct 2014),
so it should be available everywhere nowadays.
